1.	Which of the following impurities that causes corrosion difficulties in refinery operations?(a) Hydrogen sulfide and carbon dioxide(b) Hydrogen sulfide, carbon dioxide, sulfuric acid, and sodium chloride(c) Sodium carbonate and sodium silicate(d) Hydrogen sulfide and sulfuric acidThe question was asked in final exam.My query is from Environments in portion Other Environments of Corrosion Engineering
Answer» Correct choice is (b) Hydrogen sulfide, carbon DIOXIDE, sulfuric acid, and SODIUM chloride To explain: REFINERY of crude is done based on the difference in boiling points of the components present and the process is known as fractional distillation. Hydrogen sulfide, carbon dioxide, sulfuric acid, and sodium chloride are the IMPURITIES that cause difficulties in refinery operations.
